Program Levels
♦
In some cases,
RT284U finds
non-conformities
in parameter values
that must be corrected
before operating
at Basic level.
♦
The device indicates
such kind of problems
by displaying
error messages
as given on the left.
If FAiL appears
♦
on the display,
try debugging
by turning
the power off/on.
♦
If the problem persists,
press and hold
or
send command error 0
via the communication
interface to restore
the default (factory)
settings.
Basic level
At Basic level, RT284U indicates
the measured input value (PV)
with a resolution, according to
the Point Position parameter.
♦
If the whole part of PV cannot be
entirely displayed, the unit
generates blinking 'overflow'
messages (oL or -oL,
depending on PV sign).
♦
If PV is out of its operating range
(the input range according
to Table 1, extended by 5%
on both sides), the device displays
blinking symbolic messages:
<__> (under-range) or
{++} (over-range).
When PV is out of physical range,
the unit displays ----.
♦
Upon entering Basic level,
RT284U may display
the init message,
indicating that some time
is necessary for filter initialization.
♦
The noiS message may appear
as a result of the peak filter
operation (see 'Input filtration').
♦
To enter parameter value
adjustment mode for Set Point 1,
until %[1
press and hold
appears on the display.
To view the Set-point value,
release the key.
♦
To enter parameter value
adjustment mode for Set Point 2,
follow the same procedure,
but start with the
key.
Parameter Programming
12
Some parameters
are accessible only
when the respective
functionality is installed.
(see 'Specifications').
- Changing
Point Position value
reflects the real value
of all parameters
with ISU!
E.g.: changing
Point Position value
from (х1) to (х0.1)
would change
a Set-point value
of 100 to 10.0!!!
Program Levels

Controller parameters
RT284U is a programmable device whose
service behavior is determined by a set
of parameters. All the parameters, along
with their names, symbols, and value ranges,
are given in Table 1.
Setting numerical parameter value
♦
Enter parameter value adjustment mode
(see 'Program Levels').
♦
The whole part of the value together with
the left zeroes appears on the display,
and the rightmost digit blinks.
♦
To select another digit, press
♦
The 3 rightmost digits can accept values
from 0 0 0 0 to 9 9 9 9 , and the leftmost digit
can also accept the values - - - - and ` ` ` ` .
♦
To increase or decrease the blinking digit
value, use respectively
or
♦
Confirm the adjusted value by pressing
+
simultaneously
or
♦
If the new value has not been confirmed
and no key has been pressed for a certain
period of time, value adjustment
automatically ceases, and the parameter
retains its initial value.
Setting symbolic parameter value
♦
Enter parameter value adjustment mode
(see 'Program Levels').
♦
Read the blinking parameter value.
♦
To change the value, use
or
+
and to confirm, press
+
or
.
♦
If the new value has not been confirmed
and no key has been pressed for a certain
period of time, value adjustment
automatically ceases, and the parameter
retains its initial value.
Parametric level
This level contains the control
algorithm parameters. If no relay output
is installed, this level does not show up.
♦
Enter from Basic level by pressing
and holding
until PAr appears
on the display. Release the key.
If the key is not released on time,
RT284U enters Configuration level.
♦
Choose a parameter
using
and
.
♦
To enter parameter value
adjustment mode, press
♦
If no key has been pressed
for a while, the device automatically
returns to Basic level, storing all
confirmed changes.
♦
For quick exiting and saving,
use key combination
+
Configuration level
This level contains the configuration
parameters of the device.
♦
Enter from Basic level by pressing
until conF
and holding
appears on the display.
♦
To access and adjust
the configuration parameters,
follow the algorithm described
in 'Parametric level'.
